I see no need for it (-1), and don't think it is particularly GTD since it adds complexity without a corresponding uptick in task simplicity... but that said, it doesn't mean I have to use it if it is ever introduced! LOL! There are times when adding more does not affect those of us who think less is more.

This would be a very important feature for me.
For example, there are certain tasks I can only do @Home, and certain tasks that I can only do @Work, but there are also tasks that can be done both @Home and @Work. So the situation I would like to envisage here is that while I'm at work, I would like to see tasks that are marked @Work, including those that are marked both @Work and @Home. Then when I go home, I would like to see tasks that are marked either @Home or both @Work and @Home.

With the single context limitation, that means that for each task I add, I have to decide whether I can do it ONLY at home or ONLY at work, which is a big limitation to be honest. One alternative is to set tasks with no context, but then that would include other irrelevant tasks such as ones marked with @Town (meaning tasks I can only accomplish while I'm out in town).

Another alternative is to use tags instead, but toodledo only allows you to view one tag at a time.

I think a good alternative is to have a checkbox for tags and/or contexts, like in Nozbe, where you select which tags/contexts you want to view the tasks for

Another GTD cloud-based system I tried provided sub-contexts which was kind of cool. The way they implemented this was such that it didn't complicate the system for those who didn't want to use them (e.g. me). If this could be achieved here then I'd have no problem with it being added.

However if the implementation was similar to the Tag field/cloud then I'd be dead against the change.

But you know this discussion is somewhat pointless - it's not like Toodledo would be giving much weight to requests such as this.

Of course I'd like to see other fields as multi-value as well, like Location. If I have to pick something up at the grocery store, there are multiple stores in multiple locations I may be near in a day. Being able to utilize location awareness in a smart phone for more than just one location would be helpful.

Please, oh please, add multiple locations, and multiple contexts too, to your to do list. It would help me tremendously.

Also, has there been thought about raising the limit on the number of locations allowed? Last I checked there were only a 100, which seems like a lot until you start tracking restaurants, parks and other sites, that you want to visit someday.

I also agree that tags are such a mess that I've practically stopped using them. Each and every spelling error results in a bunch of tags for the same thing. This feature needs to be re-designed so there is a more secure way to add tags.

Also, why don't we have the ability to create our own field(s)? This way, we could have the flexibility to sort by as many ways as we wish.

Just a clarification on what the GTD book actually says. At no point does it *ever* talk about putting an action on multiple context lists. If you do a search on the word 'anywhere' you will see the quote that Proximo quoted, that says there are actions that can be done anywhere, and does not say to put those actions on every single context. The David specifically talks about deciding *which* context to put an action on, and not putting it on both. So the concept of checking *all* context lists that apply to your current location is very much in the GTD DNA.

What is *actually* mentioned is the 'Anywhere' context, as well as the 'Errands - Anywhere' vs 'Errands - Ojia' contexts.
You will note that 'Get Dress Socks' very clearly goes on 'Errands - Everywhere', and not on both 'Errands' contexts.

P.146 I keep two "Errands" lists—"Errands—Ojai" (where I live) and "Errands—Anywhere," for all those other things I can pick up even when I'm on the road. "T-connectors for irrigation" would go on
"Errands—Ojai," but "Get dress socks" would go on "Errands—Anywhere."

P.214: You need to decide where and how you want to do that action, in order to know which action list to put it on. Do you do this kind of thinking best on a computer, or by hand-writing your thoughts on paper? I may choose either medium, depending on what my intuition tells me. For me this next action would go either on my "At Computer" list or on "Anywhere" (because I can draw mind-maps wherever I am, as long as I have pen and paper).

P.214: If you're carrying the project notes around with you in a folder, or in a portable organizer or on a laptop, then the "Organize . . . " action would go on an "Anywhere" or "Misc." action list if you're going to do it by hand, or on "At Computer" if you're going to use a word processor, outliner, or project-planning software.
